About the CII Calculator

This tool helps shipowners and operators calculate their vessel's Carbon Intensity Indicator (CII) based on IMO regulations. By inputting voyage and fuel data, you can determine your ship's annual operational efficiency rating (A-E) and forecast future performance.

What is the Carbon Intensity Indicator?

The CII is a key measure introduced by the International Maritime Organization (IMO) to reduce greenhouse gas emissions from international shipping. It measures how efficiently a ship transports goods or passengers, calculated in grams of COâ‚‚ emitted per cargo-carrying capacity and nautical mile.

Why is CII Important?

A vessel's CII rating is critical for regulatory compliance and commercial viability. A poor rating (D for three consecutive years or E for one year) requires a corrective action plan. A high rating (A or B) demonstrates superior efficiency, enhancing the vessel's marketability and contributing to global decarbonization efforts.
